STUIVIP-MACHINE.

Specicaton of Letters Patent No. 31,386, dated February 12, 1861.

To all whom 'itmay concern:

Be it known that I, DANIEL Ins'rnn IIENnERsoN,'of Deerfield, in thecounty of IVal-ren, in the State of Pennsylvania, have invented a newand Improved Stump-Machine; and I do hereby declare that the fol lowingis a full and eXact description of the same, reference being had to theaecompz'lnying drawings and the characters of reference marked thereon.

Figure 1 represents my machine with all its parts adjusted in workingorder.

A, A, are strong upright posts wellv braced and set on a shoeor runnersas shown in drawing. Y is a cross piece, B B two ties connecting A Awith the three upright posts C, C, C. These posts C C C stand on a footD and are securely bound together by the cross piece X. This constitutesthe frame of my machine.

E, F, are levers resting on an iron fulcruin at, Y.

a is a pulley on the long end of the lever, E, over this pulley runs acord or rope M, M, M, M, one end of this rope is fastened at 18 on oneof the posts, C, it then passes over theA pulley u then down Linder thepulley s and over the shaft of the wheel and axle 14.

a a is a shorter rope attached to the long ends of the levers E, F,passing over the pulley IV on cross piece X by means of this rope whenthe lever E is drawn down, F,

lifted up.

P, P, is another rope similar to M, M, M, M, on the lever F passing overthe pulley T, and on the roller let exactly like BI, M, M, M, only withthis difference c., P P passes over the roller 14k and M, M, M, M, underthe same, and by this arrangement it is evident that on turning theroller 14 in one direction the rope M M M M is wound up and P P unwoundthus drawing down the lever E and drawing up the lever F, and byreversing the motion of 14 the contrary result is produced.

On the roller 14 are two drum wheels II, and G. On these wheels theropes N, N, N, and O, O, O, are wound in opposite directionsas are theropes M M M M and P, P. To these ropes horses may be hitched whendesired. By this construction the machine may be used by hand powerapplied to the cranks s s or horse power by attach` ing teams to theropes O O and N K is a bar of iron with slots 1, 2, 3, 4, 5 in it.On'the lower end are hooks Il to hook onto the roots of stumps; on theshort end of the levers E and F are hooks one of which is shown t' Fig.l and both of them o, S, Fig. 2. These hooks have eye bolts on theirupper end which pass through the levers and are fastened with a nut andscrew. See e' .e Fig. 1.

Fig. 2 better shows the hooks. K is the bar of iron with the slots (1 23 #t 5 Fig. 1) in it. 111, S, are the hooks of iron, 9, 10, are slidesattached to hooks o, S, and through which K passes. (3, 7, are springsattached to slides 9, 10, which throw the hooks into the slots 1, 2, 3,4t,

The machine operates as follows to wit, when the hooks L are placedunder the roots of a stump and the crank s is turned and the rope M M MM wound up. The long end of the lever E is drawn down. The hook 'v isnow in slot 4. This of course draws K up and pulls on the stump at thesame time the long end of the lever F is going up as before described,and the hook S (Fig. Q) on its short end is getting ready to pass intoslot 3 in K as soon as it shall reach it. IVhen this`is done the motionof the crank s/ is reversed and F goes down as E did and this continueduntil the bar K is drawn up to the last slot and the stump is therebyraised.

That I claim as my invention and desire to secure by Letters Patent ofthe United States is- 1. The construction of the bar K in combinationwith the hooks o, 8, constructed and combined as described.

2. Connecting the levers E and F together by the cord c e, the. sameoperated by means of the combination of the cords M, M, M, M P, P, N NN, O O. O, the pulleys U, S, T, IV, and the wheel and axle 14 G, H, whenthe same are construct-ed in the aforesaid combination and for thepurposes set forth.
